in reply to Order-Preserving and Unique: List Cleanup

If I understand what you're after then Tie::IxHash is it.

Tie::IxHash - ordered associative arrays for Perl

I has the uniqueness of a hash and the order of an array. In your case you could just use the keys and ignored the values. You can also access all normal array operations via the tied object.

[Lady_Aleena]: File::Find doesn't have a simple sub wanted example, like get the name of the file.
[Discipulus]: there is also find2perl with your perl installation
[Discipulus]: and in the wanted sub you just calculate the duretion and add it the total, stop
[shmem]: sub wanted { push @files, $File::Find::name if $File::Find::name =~/\.mp3$/ }
